For decades, the RNC/DNC has had this comfortable agreement to "contest" elections along prescribed lines, leaving each side with 45% or so of the electorate. 2016 was supposed to the same, but Trump pulled a Nelson: he's gone right up the middle, carving out massive parts of the remainder.
So now we have a minority in the RNC with no place to go - big, crony businesses in favor of open borders. After Trump grabs a big portion of the DNC middle, they too will be left with a fringe (ie the Bernie supporters).
So the challenge for any DC insiders is to somehow create a new party of these two disparate pieces, otherwise the (former) DNC/RNC will be left with 10-20% on either side, while the new GOP - re-fashioned as a nationalist/populist party by Trump - will command the middle 60%.
There are monuments & squares named after Nelson & Trafalgar, and it remains a key turning point in European/UK history. The rift Trump is creating is destroying decades of presumed national direction.
Krauthammer and George Will, along with many others, will end up in the Trump camp, I suspect before the end of the summer.
Thanks.
BTW the Dutch Admiral De Ruyter used the frontal line attack against the Brtitish nearly a century before Nelson.
